CHARLES BATGHELOR, OF NEWV YORK, AND HENRY E. \VALTER, OF CLIFTON, N. Y.

DYNAMO-ELECTRIC MACHINE.

SPECIFICATION forming part of Letters Patent No. 339,839, dated April 13, 1886.

Application filed July 6, 1885.

To (LZZ whom, it may concern:

Be it known that we, CHARLES BATGHELOR, a citizen of the United States, residing at New York, in the county and State of New York, and HENRY E. WALTER, a subject of the Queen of Great Britain, residing at Clifton, in the county of Richmond and State of New York, have invented a certain new and use ful Improvement in Electric Generators and Motors, of which the following is a specification.

The object of our invention is to produce a dynamo-electric machine which will develop a continuous current of any desired electronlotive forcewithout the use of aconimutator, and which also is capable of being used cfi'ectively as an elcctro-dynamic motor.

Qur invention consists in the novel devices and combinations of devices employed by us in accomplishing this object, as hereinafter set forth and claimed.

Our invention is illustrated in the annexed drawings, in which Figure 1 is a longitudinal section of a generator or motor embodying our invention; Fig. 2, a front view of one of the disks orsets of radial bars employed therein; Fig. 3, a front view of the other disk; Fig. 4, an enlarged section of a portion of the machine; and Fig. 5, a diagram of the internal circuits thereof.

The fieldmagnet consists of two hollow cores, 0 O, wound with coils D D, and each secured to an end plate, E. These plates are the ends of a hollow shell, F, which shell forms the yoke of the magnet. ShellFis provided with openings G G, to admit air and to make it lighter. The shell F is supported upon a 'bedplate, H, or in any other suitable manner.

As will be presently explained, the armature or inductive body consists of rotating disks or sets of radial bars. The arrangement of field-magnet just described furnishes a uniform field, in which said armature revolves, the poles of the magnet covering the whole surface of the disks, and thus there is a continuous cutting of uniform lines of force, and currents are constantly generated in all parts thereof, and there are no eddy-currents.

I is a fixed shaft, supported by blocks K K.

Upon the shaft are two separate turning sleeves, L and L. Each of these sleeves has upon it a pulley, D, whereby said sleeves may be revolved in opposite directions; also, upon each sleeve is an insulated collar or ring, 9 or g.

Secured to the end plates, E, are rods 1) I), each of which carries at its lower end aspring, brush, or other current-collector, tori. Brush '1 bears on collar g, and brush 2? on collar g. The wires 1 2 of the external circuit extend from these brushes.

One of the revolving armature disks consists of four radial bars or plates, in m m" m, the other of four opposing bars or plates, 91, a, a and a. The radial bars in m, &c., of the first-named disk extend down to the turning sleeve L, being separated therefrom by insulating material 0, which insulating material also extends up between the ends of the plates and the clamping-rings p p, which are screwed upon the sleeve and hold the bars firmly in place. The bars are mainly supported, however, from straps O O, which extend from sleeve L, and are bolted to block 1 P, of vulcanized fiber or similar insulation, to which the bars themselves are in turn secured. The radial bars are bent as shown, so as to pass between the poles of the field-magnet. At their outer ends they carry a ring or band, 8, of vulcanized fiber, which on its outer side carries four continuous metal rings, t, t, 29, and t. The radial bars are all bent out under rings 8, and are connected, respectively, to these metal rings, bar on being connected with ring it, and the other bars having connections through 8 with the other rings. The bars n it, &c., of the other disk are supported from the sleeve L in the same manner. They also extend out between the magnet -poles, and they carry at their outer ends the insulating ring 8, which has the metal rings a a n a", to which bars a, n, 91?, and n are connected, re spectively, by conductors passing through 8. Near their inner ends the bars a n, 820., carry a block, 0, of vulcanized fiber, which carries three metal rings, 10, w, and w". The bars m,

121?, and of carry each a brush or spring, as m and :v, which bear upon the said rlngs.

The bars a, n, and n are connected through block a with the rings on said block. Bar

m has no brush, and bar n has no ring-eonnection. Conductor It extends from ring 9 to bar m, and conductor it from ring 9 to bar n Bridging-connections between the disks are made by brushes 3 3 supported by the yoke of the field-magnet. The manner of these connections is shown in the diagram Fig. 5, bar m being connected with bar a, bar m with n, and so on. Thus a continuous circuitis formed, and when the two disks are oppositely revolved, so that the two sets of radial conducting-bars cut the same lines of force of the uniform magnetic field, the external circuit, 1 2, being closed, a continuous current is generated whose internal circuit is as follows: Brush 1', ring conductor k, bar m, ring t,brushes 3 y, ring it, bar n, ring to, brush or, bar m, ring t, bridging-connections (not shown) to ring u, bar 12, ring w, brush :0, bar m and so on until bar a is reached, when the connection is by conductor is to ring 9 and brush z, or the direction of the current will be opposite to this, according to the direction of revolution of the disks.

We have shown and described the disks each divided into four radial parts. It is evident, however, that any desired number of divisions may be made, the electro motive force developed increasing according to the number of divisions.

If conductors 1 2 are connected with any suitable source of electricity, the two disks will revolve in opposite directions, and either or both of them may be used as a source of motive power.- The field-magnet may be energized from circuit 1 2 or from aseparate source, as will be well understood.

A peculiarity of the machine above described is that if one disk is revolved alone 0 the other disk will receive current therefrom and will run as a motor in the same direction as the generating-disk.

What we claim is- 1. In an electric generator or motor, the 5 combination of two sets of radial conductingbars revolving in opposite directions in the same magnetic field and electrically connected together, substantially as set forth.

2. In an electric generator or motor, the combination of two sets of radial conductingbars electrically connected together and revolving in opposite directions in a uniform or practically uniform magnetic field, substantially as set forth.

3. In an electric generator or motor, the combination of the field-magnet, the two sets of separately-revolving radial bars, and the cross-connections between the bars connecting the outer end of a-bar of one set with the outer end of one of the other set and the inner end of the latter bar with the inner end. of the next bar of the former set, and so on, substantially as set forth.

4. In an electric generator or motor, the combinatiomwith two sets of radial conducting-bars electrically connected together and revolving in opposite directions, of the field'- magnet having poles practically covering the surfaces of said sets, substantially as set forth.

This specification signed and witnessed this 23d day of June, 1885.
